Fiber Laser Systems en bloc resection of bladder tumors

Fiber Laser Systems en bloc resection of bladder tumorsBladder cancer is considered to be the second most widespread urological cancer in adults and the seventh most general diagnosis of cancer in males. This type of cancer is traditionally treated by fiber laser transurethral resection. The operating principle of such fiber laser systems is based on the surgical removal of a bladder tumor from the bladder wall.

Compared to fiber laser technology, traditional techniques face several morphological difficulties and complications, for instance, possible cancer recurrence (about 60-70% of cases), detrusor muscle presence (30-60%), inability to precisely separate the tumor causing to lamina propria damage, potential tumor seeding, or incomplete resection.

Nowadays the thulium technology, based on fiber laser systems, is regarded as a new laser technique in prostate ablation onto the urological sphere. The fiber laser technology provides such benefits as the opportunity to transmit a high energy output from a relatively small optical fiber core. Compared to Holmium laser systems operating at infrared wavelengths of more than 2.000 nm, “Thulium fiber lasers operate at wavelengths of 1,908 nm and 1,940 nm, two wavelengths that match more closely with water’s optimal absorption peak”.

Thus, the fiber laser system provides a much more accurate resection of bladder cancer. The surgery by fiber lasers has been already tested and demonstrates great results. To be more precise, fiber laser technology shows its high efficiency in cases with complicated tumor locations and abnormal anatomies, for example, bladder dome tumors, tumors placed in close proximity to the ureteral orifice, and tumors that cover the ureteral orifice.

Additionally, clinical and laboratory researches of fiber lasers improve the morphological diagnostic criteria for NMIBC and give the required information about the specimen quality after thulium laser system resection and traditional transurethral resection of bladder tumor techniques.

Finally, the en bloc resection technique by fiber laser system enables it to minimize coagulation of the tumor base and urothelium along resection margins resulting in the complete impossibility of any tumor mass coagulation. Also, it should be mentioned that during fiber laser surgery all bladder layers remain saved from an intact specimen, therefore, saving the differentiation from the tumor and its base. Such fiber laser technology plays a crucial role, since laser system surgery may enable specialists to choose a more correct and appropriate treatment strategy for bladder cancer diagnoses in the future.
